Well, I read somewhere that it looks like this will crossover with NA. So it does look like he will be drwing Spidey again.
Besides, he's been working with ONLY Bendis for nearly a decade now. And one of the main things about their approach in USM, (which I actually think was one of their strong points,) was how big the scope was in involving/creating as many characters in the Ultimate U as possible. They went a very detailed universe during their run.
Basically I'm saying getting to do new characters isn't a new thing for him. He said it himself, there was so many new characters for him to play with that he found it difficult to get bored.
So yea, he's working with Bendis again, in the same vein as before. In fact, one of the last main things they did on their USM run was to introduce a female Carnage. You can't say that this isn't being repetitive on his part.
Oh, and what was his main book for MANY YEARS before taking on USM? Amazing Spider-Man!
I stand by my reasoning for saying he's incredibly habitual
